At high altitude O2 is scarce, but it still makes up the same proportion (~0.21) of the atmosphere that it does at sea level. What should be true of O2?
A) The partial pressure of O2 is the same at high altitudes as it is at sea level, but molar fraction is smaller. B) The total pressure of the system at high altitudes is the same, but the molar fraction of O2 is smaller. C) The molar fraction of O2 is the same at high altitudes, but its partial pressure is smaller. D) Both the molar fraction and the partial pressure of O2. |
C) The molar fraction of O2 is the same at high altitudes, but its partial pressure is smaller.
